I am needing to drill 30 - 36" into the end of a 1" dowel, with a half inch
bit. Built a jug, centering etc not an issue. What I am unfamiliar with is a
bit to go that deep. I tried starting with a standard 5" HSS and followed
with an electricians boring bit, but that just lost center an blew out the
side.
A quick search on google showed various places selling long bits, many
without the lead screw, which it turns out will cause tremendous damage in
end grain <g>. So I can locate a vendor, but wondering if someone might
already be buying form somewhere.
Does anybody have any experience with something like this? Perhaps someone
has a source they feel is reliable for such things?
Perhaps I am on my own!?

Split a 2x2, use a router in a table with a 1/2" ball bit to rout half
a hole in each side, glue back together, turn round.
Of course, that assumes access to a router + table, and a lathe. Or you
could use a 1" bullnose bit in the router table.

OK, this is the second time you've told us that. I'm just curious: how
do you know that you can keep the bit centered down this very long
length of dowel if you haven't located a long-enough drill bit yet?
I suppose it *is* in the realm of possibility that one could keep a 1/2"
drill bit centered inside a 1" dowel for the length of 3 feet, but I'm
skeptical.

OK, thanks for all the suggestion guys, but we missed the mark, perhaps I
should have explained what I am doing.
I need to drill these holes in 1" dowels, hundreds of them. Hence, I am not
turning these, nor routing them. As I stated, I already built a jig that
affords me dead on accuracy in test runs to center the hole, no problem
there. Somewhat of a production environment. Think of a curtain rod, 1"
dowel, 1/2" hole with a 1/2" dowel sliding into it, another short piece of
1" dowel glues on the other end. The purpose would be to "expand" the
capabilities of the rod. Make sense?
I did find a location for the bits, they are in Crystal Lake, IL. The price
is right, but they want to rape me for 16 bucks for shipping! Anybody live
by Crystal Lake, IL????
I really do appreciate the input!

Suggest square stock, split length-wise then routing each piece with a
"half round (cove?) bit, then glue up the two pieces (using a waxed
1/2" O.D. dowel or aluminum rod/tube to align, perhaps), chuck in the
lathe and round to desired O.D.
After the glue up, you might be able to run a 1/2" bit down the center
(without "blowing out the sides") to clean up the hole.
Caveat - I have never tried anything close!

2 strips of wood 1/2" x 1" x 36"
Run a 1/2" core box router bit down the middle of both strips 1/4"
down. (Use a router table)
. Glue them together (....mind the squeeze out). and round over the
edged of the square with a 1/2" roundover bit , again in a table.

Ship'a augers are designed specifically to remain centered when
drilling deep holes; however, made the assumption this was a thru hole
not a blind hole.
If blind, no way, have never seen them much longer than about 21"-24"
long.
If thru, then half way from each end.
If cost is a consideration, making two pieces and gluing together will
use lower total cost tools.
Have fun.

I did not see anything there at JD that would meet the 30+ inch requirement
anyway. Maybe I missed it??

If memory serves me correctly, you are located about 40 miles south of
"Can't get there from here", Alaska and you are complaing about
freight costs.?
Companies don't make money on S&H costs, they make it on products
unless they are sold on late night infomercials.
Maybe you should be happy some body will even attempt to ship to you.

Look, you asked for opinion/advice on dealing with your challenge. A
36" long 1/2" drillbit, of any type, is more likely to wander than
not.
There is some credence to that collective opinion.
To try to solve your challenge, a bunch of us ran some ideas up the
flag-pole.
So don't be sorry you asked, because it just might be somebody else
who's light-bulb lit up by seeing how a Wrecker's minds work.

Were I faced with this problem, I would seriously consider routing a
semicircular groove down two strips and then gluing them together. If
the hole down the middle needs to be perfectly circular throughout,
pulling a reamer through afterwards to get it to correct size sounds
more likely to work well than pushing a drill down from the ends. If
it's only a bit at the two ends that needs to be precise, then making
the central portion of the groove a bit oversized would simplify things,
too.
Finishing the outside once the hole is in the inside is, of course, a
comparatively easy matter.
Just out of curiosity, what is the final application of this? A floor
or large table lamp?

I don't know where you'll find the bit, but it brought to mind the use
of a lathe to do it.
That brought to mind the use of an 18"-ish bit to go in from each end.
BUT, that had be thinking about this... however you end up drilling it,
drill the hole in a thicker, square stock, then mount the stock on a
lathe and turn it down to a 1" dowel. That will ensure the hole is
centered.

Sounds like this is going to have to come from some sort of build up, with
the hole formed in the build, then turned true to the hole. Depth of 60-72
X dia is asking a lot.

A variation of that would be to start with a dowel that's slightly
oversized, and cut in half with a band saw. Then the OP ends up with a
rounded exterior, if that's the goal. If the glueup is any kind of
problem the oversizedness (sp?) can be trimmed on a lathe.

You're basically trying to reinvent the wheel here. Google "gun drill".
One source for the specialized pieces you need is
http://www.sterlinggundrills.com/product_prices_regrinding.shtml.
That said, for volume production routing is most assuredly feasible--it is
how pencils are made for example, and pencil factories produce them by the
million. Route the inside contour into rectangular blocks, glue them
together, then route the outside--no need to turn anything. The trick is in
the jigging and setup.

If you search for "lamp drill" or "lamp auger" or
"D bit" on rec.crafts.woodturning, you'll turn up directions for making a
proper bit for this from drill rod. It just involves a special way of
grinding a flat on the end parallel to the axis of rotation.

http://tinyurl.com/km9gdj has just what he needs, except in 3/8 and

When I used to build lamps, I would split the blank in half, run a dado
down the middle for the wire, and just drill the end to the right size
for the threaded pipe nipples...

You need a ship's auger and a brace.
